Jumpers
REF_SEL (JP1):
Selects internal or external reference
mode. (See data sheet description of REFCOMP pin.)
MSP0, MSP1, MSP2 (JP2, JP3, JP4): Manual Span
control. Setting all jumpers to the 1 position (Default)
selects SoftSpan operation, with a power-up default span
of 0V to 5V, and reset to Zero-Scale. Other options are
listed in Table 1.
LEDs
OVRTMP:
Lights when OVRTMP pin asserts, indicating an
overtemperature state. (Note that LED will light if positive
analog supply is present and OVP is not. OVP is normally
supplied by the controller.)
Test Points
The SPI bus is available on a row of through-hole test
points next to J1 that may be used to monitor the bus or
to drive the bus with an external controller.
